How to find non-https pages on a website?

Non-HTTPS websites cause modern browsers to display a "Not Secure" warning to users.

HTTPS keeps a user's connection to a server safe from tampering and eavesdropping.

HTTPS is now free, easy and increasingly ubiquitous. It's also required if you don't want browsers flagging the site as "Not secure". Yet still, many of the world's largest websites continue to serve content over unencrypted connections, putting users at risk even when no sensitive data is involved.

Use HTTPS Checker to find HTTP URLs from your domain that are still present in Google's index. The result is indicative and does not replace a complete site crawl or a technical SSL certificate check.

Redirect legacy HTTP URLs and update internal links, canonical URLs and sitemaps to their HTTPS versions.
